About this 3D model

Its just a katana, at full scale. The guard fits on the blade holder, but only from the bottom. The remaining part of the blade holder fits in the top of the hilt. Also, there are 4 inserts that are 3 mm instead of 4. they are used in the holes where the blade holder sits in the hilt. The rest is quite straight forward. Note that there is a curve through the whole sword, don't put the hilt on the wrong way.
